Be it known that we, WILLIAM KENNEDY 3 and J AMES MANFORD HUNT, citizens of the United States. and residents of Harrisonville,

. 2 is a side elevation of the same.

Cass county, State of Missouri, have invented a new and useful Improvement in Band-Tying Mechanism for Ealing-Presses, of which the following is a description.

The object of our invention is to provide a band-tyinginechanisin of such a character as `to be readily adapted to use on any of the vell-known plungerpresses; and it consists of such novel combinations of devices as are more fully hereinafter described and claimed, reference being had to the accompanying' drawings, in which- Figure l is a top plan View of so much of a plunger Daling-press as is necessary to illustrate the application of our invention. Fig. Fig. 3 is a rear elevation. Fig. 4 is a :front elevation with the' plunger driving 'mechanism removed. Fig. 5 is a detached plan view of the tying mechanism, parts being in section to more clearly illustrate the relation ofthe various elements. Fig. 6 is a detached elevation of the same.

As above stated, the drawings illustrate only so much of a baling-press as to clearly disclose the man nerof attaching ou r improved mechanism, such part being the baling-chamber and plunger-way A".

A is the plunger, which may be reciprocated in any suitable manner from the source ofi driving power, as by the pitman A', pivotally secured at its front end and traversing the receiving-chamber A", completing its stroke by entering the baling chamber A". The plunger A is provided at its lower side With two lateral and relatively diagonally dis-` posed pins or lugs C and S, each of Which lprojects through the horizontal slot in the side of the receiving-chamber, and they serve the purpose of guides for the plunger A, as well as for another purpose more fully hereinafter set forth. The plunger is also provided with the needle slots or grooves B, which extend horizontally for some considerable distance and into the face end of the plunger, as shown.

lower sides of the baling-chamber are the ,v

brackets le', which serve the purpose of pivotallysupporting the verticalshaft 7c, to which is secured, about midway of its height, the needle bar or arm K. This bar K is bifurcated atits forward end,each fork beingr bent at right angles to the body of the bar to form the nee- 'lhe point of each needle is doubly bifurcated or notched-i. e., vertically and horizontallythereby forming the four points l. Just back of the horizontal bifurcation is a small aperture extending from the forward side of the forward needlepoiut'rearwardly through the same, serving as an eye through which thebaling-wire is passed. At the pivotal point of the bar K are two cam projections R R, extending toward the baling-chamber. The measuring-wheel His pivotally secured to the rear end of the bar K, as shown, and is provided at its periphery with ratchetshaped teeth which extend nearly the entire distance around the Wheel. A segment,

however, is removed from one side of the in position by the spring f", so as to form the opening D, which when the slide F is in operative position engages with the pin Con the plunger A. A pin or lug E projects from the lower side of the bale-chamber, which when the slide F is returned to its normal position serves to engage the forward beveled end of the hook Fand to disengage the same from the pin C.

The spring-lever G is pivoted to the bracket G", is secured to the baling-chamber near its end,`aud hasa short upwardly and rearwardly extending arm which engages the inclined lug l on the lower side of the measuringwheel H. 'I he forwardly-extending portion of the lever GY is iu the formof a flat spring and engages the pin f, which extends lat- 2 eroi 5 erally from the side of the hinged member F forward of the hinge j" and serves to elevate the said hinged member, together with the hook F, into position for engagement with the pin C of the plunger A when the end of the lever G engages the lug I of the measuring-wheel H.

The slide F is provided near its rear en( with an upward projection, which serves to carry the antifriction-rollers Q, which engage the cam projections R on the bar K and operate the said bar during the tying process. The rear portion of the slide F terminates in a beveled point jm", which engages the notch li on the rock-arm J. The rock-arm .I is rigidly secured to the rock-shaft I', which is journaled in suitable brackets secured to the lower side of the baling-chamber at its rear end. To the opposite end of the rock-shaft I' is rigidly secured the rock-arm M, which actuates the tying mechanism proper.

'Ihe vertical guides N N are secured at a slight angle to the opposite sides of the baling-chamber in order that the band-tying mechanism may be secured at the proper angle to receive the band-wires as one leaves the guide c'" and the other is presented by the needles L. rIhey carry the vertically-reciprocating juxtaposed racks O O, which are splined into said guides N N. At the rear edges of the racks O Q are the lateral projections O O', from each of which extends one half ol a bearing O O", which enter the slot T ot' the link T, the link T being pi-voted to the rock-arm M. From the lateral projections O" O extend the pins P, upon which the operating-lever P is pivoted, the oscillation of which lever gives relative movement to the racks O O. At the sides of the guides N N are secured the C-shaped bearings U, as shown in Fig. 3, or said bearings may be located in a plate U, as shown in Figs. 5 and (i, and secured to the guides N N. The inner sides of the guides N N are open toward the bale-cham ber. V V are the tying-wheels, which are provided with the trunnions V' V', carried b v the bearings U U. These wheels are juxtaposed and are provided with six teeth, each ot' which mesh with the teeth ofthe racks O O, the spaces or grooves between the wheel-teeth extending-some depth into the body of the wheels and their trunnions, as shown in Fig. 2.

At the forward ends of the bale-chambers are located the wire-reels c c, the number of such reels being double the number of the bands used in baling, two band-wires-one from each side of the press-being used in forming each band. The wire c" from the needle-bar side of the press is carried through the guides c", over the tension-pins 0", through the guide om, through the'needleeye Z on the needle bar, and through the needle-slot in the side of the bale-chamber, while the opposite wire is similarly threaded through guides c" and c" and over the tension-pins 0"", the ends of thejtwo wires being tied in any suitable manner in the chamber. When the needles are so threaded, the mechanism is ready'for operation, which will now be described.

With theparts in position as shown in Fig. 1, hay or other material to be baled is fed into the space A"',and the plunger A, being driven by any suitable power, presses the hay into the chamber A", carrying with it the tied bindingwires. As the plunger is drawn back more hay is fed into the space A, and the operation is repeated until the compressed hay cominginto contact with the measuringwheel `H rotates the same until the lug I on its under side contacts with the lever G, thereby raising the spring end of said lever and carrying with it the forward pivoted end F' on the slide F.

and the opening D and carry with it the slide F. The further movement of the slide F brings the rear roller Q into contact 'with the rear cam R upon theneedle-bar K, thereby driving the needles L through the openings Z" and slots B in the plunger A to the position shown in dotted lines in Fig. l. In the meantime the projection f'" has engaged the notched rock-arm J and rotated it and the rock-arm M into the dotted-line positions, as shown. the arm M carries with it the strap-link T and racks OO. During the process of filling the bale-chamber the wire C' has been drawn by the bale between the teeth of the wheels V, and now with the wheels in the position shown in Fig. 5 these wheels are rotated by the upward movement of the racks O O, thereby giving the wires a twist, as shown. As the plunger approaches the end ot' the stroke the pin S will engage the operating bar or lever P, which is of cam shape, and rotate it upon one of the pins P, thereby giving relative movement to the racks O O and through them to the wheels V V, which now have the twisted sections of the two wires c and c" located in diametrically-opposite grooves,thereby shearing the two wires between the twists or knots. The return stroke of the plunger A carries with it the slide F, which now permits the rock-arm J and, through the connecting mechanism, the twisting or lying device to resume their normal positions. When the plunger has made somewhat more than half of its return stroke, the hook F" will engage the pin E, thereby releasing the pin or lug C and leaving the slide F and needle-bar Kin the position shown in full lines in Figs. I

and 2, ready for the next bale. It should be here noted that of the two twists or knots one is upon the bale and the other connects the two wires Cand C" for the next bale. Upon the restoration ot the needle-bar K to the position shown in full lines in Fig. l the measuring-wheel H will again come into contact with the bale just bound. Should, however,

such wheel H have slightly turned during the tying process, the end ot' the flattened por- At the next stroke of thei plunger A the pin C will engage the hook F",

The upward movement of IOS against the bale.

tion will come into contact with the bale lrst, and further pressure. due to the action of the needle-bar, will force said iiattened portion In this manner the bales are all made of a uniform size.

From the description,in connection with the drawings,it will beseen that our tying mechanism is automatic and needs no other attention than that of supplying the baling-chamber with material to be baled and that. when a bale of proper size has been made the measuring-wheel trips the tying mechanism, all parts being operated by the movement of the plunger.

We do not limit ourselves to the precise mechanism shown and described, as manyminor changes may be made without changing the scope of our invention, and all such changes as come within ,the spirit of our invention we desire to cover.

Having now fully ascertained the construction and method of operation ot our invention, what we claim, and desire to secure by Letters Patent-of the United States, is-
